PROCESS OF AND MACHINE FOR COVERING PULLEYS, 80C.

SPECIFICATION forming part of Letters Patent No. 249,525, dated November15, 1881.

- Application filed April 18, 1881. (No model.)

To allwhom it may concern:

Be it known that I, WARREN HOWARD, residing in the city and county ofWorcester, State of Massachusetts, have invented a new and useful Mannerof Covering Pulleys and other Articles, and Machine for the Same, ofwhich the following is a specification.

My invention relates to covering pulleys and other articles with acoating of leather or other suitable material in a peculiarmanner,whereby I can make either the flat side or edge of the materialthe finished surface,

The accompanyingdrawin gs represent amachine for my manner of coveringpulleys.

Figure l is a front view, showing the pulley A partly covered. Fig. 2 isaside view with a part of the frame left off; and Figs. 3 and 4 showsome parts hereinafter more fully described.

Myiuvention is particularly adapted to using the waste trimmings ofleather for card-clothing, though various other stock, as leatherboard,the trimmings of boot and shoe stock,

or similar material, may be used to advantage.

The stock being prepared by forming into a strip of uniform size, it isfed into the machine as at 11, Figs; 1 and 2, passingundera roll on theshaft 19 in the cement-pan P, from whence it passes up to the guide B,taking sufficient cement with it, and by the guide B isheld in properposition and laid on the pulleyA, which has raised edges or guards to,against which the outside edge of the first and last turns of thecovering are laid, .and by them protected and held. The pressing-roll Opresses the material onto A, and also firmly against the side of theturn just laid, the roll 0 having aflange, r, Fig. 4, for that purpose.Both the guide B and roll 0 are attached to the bar F, which slides onWays on the frame 1 l, and has a nut, h, securing it to thescrew,whereby it is moved regularly across the surface of the pulley Aas the covering progresses. At E is a knife set in a slide, d, and heldup by the spring c,hav-

ing its edge parallel to the raised edge of the pulley A. When the bar Fhas moved across the surface and the pulley A is fully. covered aprojection, b, on the bar F strikes an incline on the knife E, forcingit down and cutting off the covering-strip a. by a slanting out, whichfits the rim a, and also leaves the end in the right form to begin on anew pulley. The rims of the articles'to be covered are made with raisededges a for holding the ends and protecting the edgeof the covering allround them. The articles, While being covered, are

ter in the tub L, and thus either glue or oe ment may be used, asdesired.

It will be seen that the strip a may be put onto the pulley A eitherfiat or edgewise, as preferred, by fitting the guide B to it, whichguide may be in twoparts, adjustable by a connecting-screw to fitdifferent sizes. Thus either the grain or flesh of leather or its edgemay be made the finished surface; and with any other material,where theedge of the strip has any advantages, it may be used as desired, andthus a covering of any thickness be made.

I am aware that articles have been covered by a strip wound spirally on.These I do not broadly claim; but

What'l claim as new, and desire to patent, is-- 1. The manner of windinga strip (either flat or on edge) around the surface between the tworaised guards which protect and hold the covering on the pulley by themechanism substantially as described.

2. In a machine for covering pulleys, the guide B, in combination withthe sliding'bar F and a mechanism for giving motion to the sliding bar,substantially as and for thepurposes set forth.

3. The pressure-roll U, arm D, with sliding bar F, and mechanism forgiving them motion across the face of the pulley, substantially asdescribed.

4. In a machine for covering pulleys, the knife E, substantially asabove described.

WARREN HOWARD.
